3. Na ho na le kamano pakeng tsa lerotholi la putty powder le HPMC?

Tahlehelo ea phofo ea putty powder e amana haholo-holo le boleng ba molora oa calcium, 'me ha e amane hakaalo le HPMC.Khalsiamo ea khalsiamo e bohlooho le karo-karolelano ea CaO le Ca(OH)2 ka k'halsiamo e grey ha li tšoanelehe, e leng se tla baka tahlehelo ea phofo.Haeba e na le ho hong ho amanang le HPMC, joale ho boloka metsi a futsanehileng a HPMC ho tla boela ho baka tahlehelo ea phofo.

4. Ke bokae ba hydroxypropyl methylcellulose (HPMC) ka putty powder?

Palo ea HPMC e sebelisoang lits'ebetsong tse sebetsang e fapana ho latela boemo ba leholimo, mocheso, boleng ba calcium ea molora oa lehae, foromo ea putty powder le 'boleng bo hlokoang ke bareki'.

5. Viscosity e nepahetseng ea hydroxypropyl methylcellulose (HPMC) ke efe?

Ka kakaretso, li-yuan tse 100,000 tsa putty powder li lekane, 'me litlhoko tsa seretse li holimo,' me li-yuan tse 150,000 lia hlokahala bakeng sa tšebeliso e bonolo.Ho feta moo, mosebetsi oa bohlokoa ka ho fetisisa oa HPMC ke ho boloka metsi, ho lateloa ke ho teteaneng.Ka phofo ea putty, hafeela ho boloka metsi ho le molemo 'me viscosity e tlaase (70,000-80,000), hape e ka khoneha.Ha e le hantle, ha viscosity e phahame, ho molemo ho boloka metsi a lekanyelitsoeng.Ha viscosity e feta 100,000, viscosity ha e na phello ea ho boloka metsi.e kgolo.

6. Mokhoa oa ho khetha hydroxypropyl methylcellulose (HPMC) e loketseng merero e fapaneng joang?

Kopo ea phofo ea putty: litlhoko li tlase, viscosity ke 100,000, e lekane, ntho ea bohlokoa ke ho boloka metsi hantle.Kopo ea seretse: litlhoko tse phahameng, viscosity e phahameng, 150,000 e molemo, kopo ea sekhomaretsi: lihlahisoa tsa hang-hang lia hlokahala, viscosity e phahameng.

7. Tšebeliso ea HPMC ka putty powder, ke lebaka lefe la li-bubble ka putty powder?

Ka putty powder, HPMC e bapala likarolo tse tharo tsa ho tiisa, ho boloka metsi le ho haha.Se ke oa kenya letsoho liketsong leha e le life.Lisosa tsa bubble:
